1969 All with 302 or 350 - P/N 6470008 stamped 40669. The one Marty shows is correct, but HERE'S the direct link to the auction. That one happens to be a repop, but you can also buy rebuilt from just about all the vendors. It's unknown what the two digit code in front of the 40669 is, but I've seen HH, 4K (like the one on ebay), FI, UH, etc... Perhaps a date code? John might know.

That 2-digit code appears to be an AC date coding; David Liukkonen on the NCRS Tech Board is working on the complete decode matrix, and will publish it when he has more data.

Thought I would re-kindle or try as you did Darrell almost a year ago. Any news on this JohnZ or anyone concerning stamp codes being published? Believe some of us have what we think is correct for 1st gen Camaro's but it does become confusing on when the Julian date codes started and the subsequent letter for years as certain letters had multiple year meanings apparently.
